[0030] Working principle:

[0031] The vehicle battery pack body 7 is placed on the upper surface of the top plate 12 to prepare for the subsequent anti-collision testing of the vehicle battery pack body 7 .

[0032] Car battery pack limit work:

[0033] When the external power supply of the electric telescopic rod 806 is turned on, the electric telescopic rod 806 starts to drive the square plate 805 to move downward. The downward movement of the square plate 805 drives the two connecting rods 804 on both sides to swing downward, driving the clamps 803 on both sides to slide relatively on the slides processed on the inner wall of the second shell 801. At the same time, the clamps 803 on both sides slide relatively on the surfaces of the round rod 802 and the slides processed on the second shell 801, clamping and limiting the vehicle battery pack body 7. After the vehicle battery pack body 7 is limited by manual observation, the external power supply of the electric telescopic rod 806 is turned off.

[0034] Car battery pack anti-collision work:

[0035] When the external power supply of the first motor 9 is turned on, the first motor 9 starts to drive the threaded rod 11 to rotate in the base 1. The rotation of the threaded rod 11 drives the threaded seat 10 to slide to the right on the inner wall of the base 1 and the slideway processed on the base 1, and drives the automobile battery pack body 7 to move to the right and hit the collision plate 3 to perform anti-collision work.

[0036] Anti-collision detection and fire extinguishing work:

[0037] When the automobile battery pack body 7 catches fire due to collision, the hose 6 is connected to the external material box, and the dry powder in the material box is sprayed out from the opening at the lower end of the material delivery pipe 4 to the automobile battery pack body 7 through the hose 6 by the material pump. At the same time, the external power supply of the second motor 507 is turned on, and the second motor 507 is started to drive the thick rod 502 to swing left and right. The swing of the thick rod 502 drives the thin rod 506 to move left and right, drives the cross bar 503 to move left and right in the vertical plate 504, and drives the vertical rod 505 to slide left and right on the slideway processed on the first shell 501 (such as Figure 5 ), driving the conveying pipe 4 to move left and right to fully spray dry powder on the automobile battery pack body 7 to extinguish the fire.
